This study determined the effects of organic and inorganic fertilizers on growth yield three pepper cultivars in Mount Cameroon Region. Pepper seedlings were treated with six treatments (T1 = no (control), T2 250 Kg/ha NPK 20:10:10, T3 350 T4 450 T5 20 Mg/ha poultry manure (PM), T6 30 PM). The had a significant effect vegetative Capsicum chinense cv. “Big Sun” plants maximum plant height (39.09...

ABSTRACT- The aim of this study is economic analysis of supplemental irrigation (SI) for rain-fed fig trees in the south of Iran, with and without micro-catchment water harvesting systems (MCWHS). Under no MCWHS, by decreasing about 55 % of applied water, the fig yield decreased about 28% and net income increased twice compared with the maximum yield condition. In general, the ...

We describe a MATLAB implementation [6] of the method LSTRS [5] for the large-scale trust-region subproblem:

background and objectives: quinoa (chenopodium quinoa willd.) is a member of amaranthaceae family that originated in the andean region in bolivia, chile and peru five thousands of years and so it has a tiny and round seeds. quinoa in different combinations of food used as food, as well as how to cook like rice grains and known as the inca rice in the south american countries. the high nutrition...

The main purpose of this work is to determine the forward and backward solution space of a nonregular discrete time AR-representation i.e. A(σ)ξ(k) = 0, in a finite time horizon where A(σ) is a polynomial matrix and σ is the forward shift operator. The construction of the behavior is based on the structural invariants of the polynomial matrix that describes the AR-representation i.e. the finite...

A closed formula is given, which allows the determination of the impulsive solutions of Linear Homogeneous Matrix Differential Equations (L.H.M.D.E.) directly in terms of finite and infinite spectral data of the associated polynomial matrix. Specifically the notions of finite and infinite Jordan pairs for a general polynomial matrix are defined and it is pointed out the strong relationship amon...

Field experiments were conducted to study the effect of organic matrix based slow release fertilizers (SRFs) on plant growth, nitrate assimilation and seed yield of Brassica juncea L. cv, pusa bold. The agro-waste materials like cow dung, clay soil, neem leaves and rice bran were mixed together in 2:2:1:1 ratio and used as organic matrix for the immobilization of chemical fertilizer nutrients w...

Transgenic cotton plants (Bacillus thuringiensis Berliner (Bt)) has significant influenced the integrated pest management around world. In Colombia, Anthonomus grandis Boheman and Spodoptera complex are currently considered main pests in crops. Therefore, this study evaluated effect of Bt (Cry1Ac Cry2Ab) non-Bt on population fluctuation during two years Tolima region. A Pearson correlation matr...
